Well-tubing and means for connecting sections thereof.



UNITED STATES PATENT OFFICE.

GUSTAVUS ADOLPI-IUS PITTMAN, OF DEWEESE, NEBRASKA.

WELL-TUBING AND MEANS FOR CONNECTING SECTIONS THEREOF.

To all whom it may concern:

Be it known that I, GUsTAvUs ADoLPHUs PIITMAN, a citizen of the United States, and a resident of Deweese, in the county of Clay and State of Nebraska, have invented a new and useful Improvement in \VelLTubing and Means for Connecting Sections There of, of which the following is a full, clear, and exact description.

This invention relates to well tubing and has for its object to provide a well tube of any length, from vitrified clay, formed in sections before baking the same, and also provide clamping means for joining the tube sections together endwise, thus producing a lining tube that will be inexpensive, practical and durable, and which may be placed in a well bore or removed therefrom with the same means used to insert and remove iron lining tubes.

The invention consists in the novel construction and combination of parts, as is hereinafter described and defined in the appended claim.

Reference is to be had to the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a side view of two well tube sections, shortened in length between their ends, the latter having a feature of the invention thereon, the sections being connected endwise together, and secured by a clamp, which is constructed for co-action with the novel details on the tube sections; Fig. 2 is a longitudinal sectional view of two tube sections broken away, and of the improved clamp, the section being taken through the axis of the tubes, substantially on the line 22 in Fig. 4; Fig. 3 is a side view of two well tube sections similar to the tube sections in Fig. 1 and connected to gether by the improved means, seen in the direction of the arrow m in said figure; and Fig. 4 is a transverse sectional view, substantially on the line 4 l in Fig. 2.

In the drawings, 5 indicates a section of a well tube, which may be of any preferred length and diameter, having a cylindrical body, the wall thereof being proportioned in thickness so as to afford necessary strength. The ends of the well tube sections 5 are rendered flat and true, so as to have close contact one upon the other when the tube sections are connected in sequence.

Specification of Letters Patent.

Application filed August 15, 1908.

Patented Nov. 23, 1909. Serial No. 448,682.

At each end of a tube section 5, two lugs a are integrally formed, that project outward at diametrically opposite points, said similar lugs, having suitable dimensions for strength and preferably a rectangular form, are impinged upon like lugs when'two tube sections are abutted upon each other and axially alined.

The preferred means for securing the tube sections 5 together in any desired number, for the formation of a tubular lining for a water or oil well, comprises a clamping band 6, formed of plate metal bent into cylindrical form. The interior diameter of the band 6 is slightly less than the exterior diameter of the tube sections 5 said band is to be secured upon, and at the ends of the open band similar flanges 6 are bent, that project radially therefrom and which will closely approach when said flanges are drawn toward each other.

Suitable perforations are formed oppositely in the flanges (3 for the reception of short screw bolts 7, that when the band is to be secured upon two tube sections 5, are inserted through the pairs of opposite perforations and engaged at their threaded ends by nuts 7*.

In the band 6, at diametrically opposite points, two rectangular perforations b are formed, wherein the pairs of lugs a are respectively inserted when the band 6 is in an opened condition, placed around two alined tube sections 5 at their meeting ends. The pairs of lugs 64 respectively fit closely in a corresponding perforation b, and it will be seen that when the flanges 6" are forcibly drawn toward each other by means of the bolts 7 and nuts 7 the tube sections 5 will be clamped in axial alinement, as is represented in the drawings.

Obviously a well tube constructed in the manner described, will be as rigid and strong where joined together as at other points, and that a tube thus formed in sections may be lowered in a well by the usual means and removed therefrom as may be desired.

It is to be understood that tube sections may be formed of terra-cotta or cement molded and subsequently dried. It is preferred, however, for sanitary purposes, to employ material similar to that used for the manufacture of drain tile or roofing tile, and glaze the interior of the tube sections.

It will be seen that by the means employed in pairs for connecting sections of a well tube, the tube may be passed down through quicksand, as the tight joints between the sections permit the tubing to receive a sucker and rod carrying it, so that the sand and water may be pumped up through the tube, and the Well deepened until the quicksand is removed and boring of the well may be resumed.

Having thus described my invention, I claim as new and desire to secure by Letters Patent:

In combination a plurality of tubes placed end to end, each of said tubes being provided at its end with oppositely arranged projecting lugs, the end face of the lug registering with the end of the pipe the lugs at the abutting ends registering with each other, and a clamping band encircling the tube and provided with openings through which project the lugs, said band having its ends flanged and provided with registering perforations, and bolts traversing the perforations for clamping the band on the tubes.

In testimony whereof I have signed my name to this specification in the presence of two subscribing Witnesses.
